Palladium nanoparticles of 3.2 ± 0.9 nm size were generated within 12-18 mesh pellets of hybrid zirconia/polyvinyl alcohol matrix, to afford a 0.03-0.1% Pd loading (w/w). The material was used in the catalytic, continuous flow hydrogenation reaction of multiple C C and C C bonds and nitrobenzene, showing good selectivity at full conversion and excellent resistance over prolonged time-on-stream under, room temperature and 1-2 bar H2gas. No metal leaching in solution was detected as well as no additives nor regeneration steps were needed for use in hydrophilic solvents.

Abstract

Palladium nanoparticles of 3.2 ± 0.9 nm size were generated within 12-18 mesh pellets of hybrid zirconia/polyvinyl alcohol matrix, to afford a 0.03-0.1% Pd loading (w/w). The material was used in the catalytic, continuous flow hydrogenation reaction of multiple C C and C C bonds and nitrobenzene, showing good selectivity at full conversion and excellent resistance over prolonged time-on-stream under, room temperature and 1-2 bar H2gas. No metal leaching in solution was detected as well as no additives nor regeneration steps were needed for use in hydrophilic solvents.
